Background and aim of the study: True parachute mitral valve and parachute-like asymmetric mitral valve are associated with congenital anomalies of the papillary muscles, which involves an abnormal anatomy of the papillary muscles and chordae.

Methods: Two patients are described with mitral valve regurgitation and papillary muscle anomalies. Mitral valve repair using artificial chordae reconstruction and ring annuloplasty was attempted in both cases.

Results: The first patient had a true parachute mitral valve, while the second patient had a parachute-like

asymmetric mitral valve. In both patients, widespread leaflet prolapse induced mitral valve regurgitation, and the anterior mitral leaflet was thickened because of long-term regurgitation. Mitral valve repair using artificial chordae reconstruction and ring annuloplasty were successfully performed. At midterm follow up the patients did not experience any progression of significant regurgitation or stenosis.

Conclusion: Mitral valve repair using artificial chordae reconstruction combined with ring annuloplasty is effective for treating regurgitant parachute mitral valve in adults.
